VARIABLE SPEED
The saw is equipped with a variable speed control (0 to 2600 SPM). As the
switch trigger is squeezed, the speed of the saw blade increases.
The lower speeds are recommended for most metal cutting, while the higher
speeds are recommended for wood. A few practice cuts at various speeds
(on scrap material), will aid you in choosing the best speed for obtaining the
desired results on your application.
DUAL BLADE MOTION (Model 747 only)
The Model 747 has dual blade motion: you have a choice of straight
reciprocating motion, as shown in Fig. 10, or orbital motion as shown in Fig.
11. Straight reciprocating motion should be used for all metal cutting
operations, and for wood cutting applications where finish is more important
than speed. Orbital motion is used for fast cutting of wood.
To set saw for straight reciprocating motion: rotate knob (A) Fig. 10,
clockwise so that the bar is vertical (opposing arrow symbol up), as shown
in Fig. 10.
To set saw for orbital motion: rotate knob (A) Fig. 11, counterclockwise so
that the bar is horizontal (oval arrow symbol up), as shown in Fig. 11.
DO NOT USE THE TOOL IF KNOB (A) FIG. 10 & 11 IS
BROKEN AS EXPOSED METAL PARTS MAY BE MADE LIVE IF THE BLADE
CUTS INTO LIVE WIRING WITHIN A WALL.
